But now, thanks to the wonder of changing language, translucent is also going to have to mean transparent, or semi-transparent. Pellicle, semi-silvered, whatever term you wish to use.

Unfortunately, for this writer the misuse of the word translucent stands as one of the biggest schoolboy howlers ever imposed on the entire world by the ignorance of a corporation. It’s such a glaring error I can hardly bring myself to use the term – others, like Dave Etchells, have happily assimilated the new meaning into their technical lexicon. And as the video above shows, they’ve made it into a trademark, a permanent part of the future of this technology.

Wiki, and pretty well every dictionary ever published, disagree with Sony’s imaginative use of a word from which they have now removed its exact meaning:

Wikipedia: “Transparent materials are clear, while translucent ones cannot be seen through clearly.”

Merriam-Webster:

trans·lu·cent/transˈlo͞osnt/

Adjective: (of a substance) Allowing light, but not detailed images, to pass through; semitransparent.

(the semi bit of semitransparent cited here seems to mean semi-detailed, vaguely delineated – not slightly darker; otherwise the primary definition of the word is diluted).

There has been some heated argument on dPreview forums about this post of mine (my view is shared by many). No-one has made the point that words evolve to have useful exact meanings. Transparent and translucent are words which may once have shared a common poetic meaning in 18th century descriptive writing, but whose meanings were refined with the progress of science and technology. This process in the course of over 200 years resulted in a useful distinction between the meanings of transparent and translucent. Sony’s commercial misuse of the word Translucent is damaging to the English language and to the scientific and technical lexicon; it predisposes future confusion about the meaning of the words.

It is also a fait accompli; there is no turning back, since Sony’s corporate stance is much like that of Mrs Thatcher; no u-turns and never admit to be being wrong. They have also no doubt invested hundreds of thousands of dollars in the consultancy involved, and the registration of the term as a trademark, the creation of branding artwork.

They could have branded the mirror TransLumina® or, more usefully, just called it a transflecting mirror – transmitting-reflecting. That term is already used to describe the sort of mirrors used in ‘Big Brother’ with cameras behind them.

As to whether it’s a true pellicle mirror (a thin stretched film of vacuum coated Mylar or a similar polymer) no-one seems to be clear. It moves out of the way to allow sensor cleaning but could be relatively fragile. It certainly does not need to move to allow 10fps (Alpha 55) or 7fps (Alpha 33) continuous shooting. Sensor dust is often created within the camera by wear and tear on the shutter mechanism, so access for cleaning is essential and the mirror can not be designed to seal the sensor chamber. The Alpha models still have a shutter, that’s the next thing we shall see eliminated. That old rumour of the 15fps silent shooting Alpha DSLR seems to be more than a rumour; we are almost there.

For many users, the critical advantage of all four new Sony models will be HD Video with sensor-based in body image stabilisation. This will enable all kinds of lenses from macro to ultrawide or soft focus, manual adaptations and Minolta AF legacy glass to be used for video with confidence.

Welcome back the circular polariser, unlike mirrorless ILC cameras these new models will not allow the use of linear polarisers without AF efficiency reductions, but exposure should be unaffected as the sensor itself provides the metering with 1200 zones.

This will be one of the tests reviewers need to carry out on the new pellicle mirror Sony Alpha 33 and 55 models – to confront them with not only polarising filters, but conditions in which light is naturally polarised. How will they render sky gradations or reflections off water?

Two further Alpha models are being released, which are essentially updates for the 500/550 – the Alpha 580 which will hit the shops before the winter buying season, adding 16.2 megapixels and a 15-zone AF module, HD 1080p video and (non-video) Contrast Detect AF with all Alpha mount lenses. The 560 will not arrive until some time in 2011, using a 14.2 megapixel sensor.

Versatile features

More of a landmark than a benchmark, the inclusion of 10fps continuous shooting with active phase detect AF and 16.2 megapixel file size in the Alpha 55 is unprecedented and possibly unforeseen by competitors, in this class of sub-$1000 consumer DSLR (let’s continue to use the term, since they are clothed as DSLRs). The dual format card drive supports the 30Mb/s transfer rate of the latest Class 10 SDHC cards and Sony’s fastest MemoryStick Pro Duo generation. The HD video also has a reasonable 17mbps  bitrate.

The new technology has been well documented before the launch, but the fine detail of the new cameras is now clearer. The Alpha 55 is some markets will incorporate GPS geo-tagging for stills and videos (we wait to see whether raw files are tagged, and how accurate this is – the accessory Sony geo-tagging system available to date has only permitted JPEG tagging, and has not been accurate enough to know which street in a town the picture was taken in).

Rumours that the 33 and 55 bodies would be SSM/SAM only, with no internal focus drive, were unfounded as Sony states clearly that both are compatible with ‘the full range’ of over 30 Alpha lenses (indeed, the product shots of the 33 and 55 alone show the 18-200mm SAL DT lens fitted). The 55/33 1080i/60p (1080p in AVCHD camera archive format) video claims ‘smooth, precise’ phase detect auto focus during video shooting, but makes no reference to this being limited to in-lens motor lenses. Therefore we can assume it works with in-body AF drive lenses as well, and you just have to edit the soundtrack.

The new ISO 25,600 mode does not imply a radical sensor change as it is only available using Multi-Shot Noise Reduction, which requires a burst of 6 frames at the 10fps/7fps native maximum speed of the camera, and can not save raw files. The ISO range of the sensors is 100 to 12,800. Is this range quoted as absolute, or after accounting for the semi-silvered mirror light losses? If it’s the range before allowing for the mirror, then the 14.2 megapixel sensor of the Alpha 33 may be more like the Nikon 3100′s sensor than the NEX (ISO 200-12,800) is.

Thom Hogan has shown pixel dimensions and size data which support Nikon’s claim to have an entirely different sensor fab line of their own, compared to the A550/NEX sensor. But how about compared to the A33/560 sensor?

The 55′s new 16.2 megapixel CMOS will probably appear in the forthcoming Alpha 700 successor, which it is believed will form the main Sony exhibit at photokina (Cologne, September 21st-27th). Both models have a new 15-zone AF sensor with three cross sensors, but not f/2.8 sensors – all are designed to operate at f/5.6 virtual aperture. However, there is a hidden clue that the cross sensors may be f/3.5 capable, as the high-speed shooting modes with continuous AF set f/3.5 by default on any lens capable of this (if the lens is, say, only f/5.6 then the largest aperture is always set). Setting f/3.5 implies that this confers an advantage in focus sensitivity over f/5.6, f/4 or any other particular aperture – and that f/3.2, f/2.8 or wider would bring no benefit. That points to some of the sensors having an f/3.5 virtual aperture.

The new cameras are known as SLTs – Single Lens Translucent – instead of SLR. See my intro. Did they have no English speaking staff on their team? I’m sure there is a German word which describes their mirror correctly. I’d rather have the right German word than the wrong English one. Ah well, as the bloke leaning on the pub bar says, durchsprung vor technik…

Confusing aspects – Auto HDR is said to be available in P/A/S/M modes. I guess in M mode it must leave the aperture alone and change just the shutter speed. Regular bracketing is still limited to a disappointing 3 exposures at 0.7 EV intervals, maximum.

But you’ll love the direct D-Range button which gives access to D-Range and HDR options directly, and the direct Finder/Screen button which toggles between using the very high resolution EVF with its ‘virtual 1.1X’ 100% view of the subject – effective visual scale, larger than the Alpha 700 and larger than any previous Alpha digital model except the Alpha 900 and 850. That’s one of the benefits of the EVF, a relatively tiny display is viewed through a high magnification ocular and ends up with a ‘window’ on the world which beats the tiny tunnel vision of optical finders. Technically it is very similar to the last EVF produced by Konica Minolta on the Dimage A200, with the benefit of five years’ further development. It has the same 60Hz refresh rate and visually almost raster-free RGB.

Where the A550 and its earlier stablemates vary slightly around a viewfinder with an effective 0.50X scale (relative to a full frame 100% view using a 50mm lens), the A55 and A33 provide an effective 0.73X and that’s impressive. The ocular is set well back (remember the Konica Minolta A2, and the Sony Cybershot DSC R-1?) because it is a telescope design. This also gives it a very narrow range of possible eye positions, a common feature of EVFs. The eyepoint is close, and you must position your eye precisely.

The rear screen uses the same type of (Schott?) reinforced glass with (3M?) resin gel adhesive as Canon’s 7D – this totally seals to the LCD module itself eliminating air gaps, and improves contrast. It is a technology first seen in the 7D and becoming standard across the industry though the NEX has shown Sony to have the best implementation so far. It is scratch proof, by the way, and it can be cracked by impact like any other screen.

The tilt-swivel action is borrowed directly from the Nikon D5000. In fact, it’s so identical in articulation it even included the amazingly silly front facing mode where the screen is obscured by your tripod, hanging under the camera and preventing it from being placed on a flat surface for self-portraits or videos. But it has the same benefit as the Nikon, the screen can be flipped to face the camera and protected completely while you use the EVF.

Functions familiar from the NEX including Sweep Panorama and Sweep 3D Panorama are built-in and accessed from the main mode dial, which also provides physical settings for all the main modes. Depth of field preview is restored – with the usual button – because is can now actually work. It was always useless in real terms on optical viewfinder cameras, as the focusing screen never represented wide apertures correctly.

Now, with an EVF, for the first time ever an eye-level Alpha gives absolutely perfect and precise previewing of depth of field and bokeh effects whatever aperture you are working at – even at f/1.4, which was never possible and still isn’t with the A850 or A900 for that matter (which is why their Preview mode is useful).

You can also preview the exact image appearance. By pressing the AE lock button, the auto gain of the EVF or rear screen are turned off and replaced by an exposure-compensated view. So if you dial in -1 EV (using the adjacent dedicated button), and change the WB, and use a different picture style with more saturation and contrast just pressing AE-Lock will immediately preview your image with these adjustments applied. And you can enlarge in the usual two steps to check auto or manual focus.

The finder and screen also have a Nikon-style two axis spirit level (flight simulator horizon) display to help you get your horizontals straight and your verticals parallel. It can be activated on either, and does not have to appear on both simultaneously.

For movie makers, the binaural stereo microphones are a great move. Even on the NEX, the two small top aperture mics give excellent stereo. The 33/55 mics are placed either side of the ‘prism’ housing, rather like the ears on your head. This will give the stereo image created by these cameras a really natural quality. Natural, that is, to a pygmy marmoset monkey… but still, I will wager, the best stereo image of any DSLR/HybriD. And Sony provide a stereo 3.5mm mic jack socket, though without any manual control of gain levels.

I’m sure we will have to buy the A780 to get that. Click the picture above for a big version. Who says Sony does not have a range to match Nikon or Canon, whether or lenses or of cameras? From the left, the cameras show the current range before we even see the magnesium-bodied Alpha 700 replacement arrive. A900, A850, A580, A560, A55, A33, A390, A290.

So, I copied my ramblings and moved them here, instead of putting them in a forum post where just a few hundred people would see them. Tens of thousands of visitors see Photoclubalpha’s main site articles, and I want this to be seen, because it matters.

PP’s write-up is very positive – it is not a ‘bad review’ in that sense – but much of the wording used is misleading, and omissions can sometimes distort the comparison a reader makes.

PP starts off by saying the NEX-5 has ‘the added advantage of HD video’ over the NEX-3 – of course, both have HD video, the NEX-5 is 1080/50i AVCHD while the NEX-3 is 720/25p MPEG4. It could be assumed that the PP reader has only a marginal interest in video, but this phrasing does not describe the feature and implies that the NEX-3 lacks HD video.

The screen is great for ‘low level composure’  and the APS-C sensor is ‘ideally placed for delivering DSLR quality images’.

The majority of the selecting, PP says, is done through ‘never get lost’ menus (sounds as if PP were fed a marketing term here – I would probably call some of them ‘dead end’ menus in maze terms – you have to return or exit). Confusingly, PP says there is ‘no dual sensor cleaning, but there is an electromagnetic vibration system and an anti-static coating on the sensor’. I thought this was a dual anti-dust measure. What is ‘dual sensor cleaning’ if it’s not this, and how does the NEX lack it?

PP also says that removing the lens reveals how close to the rear element the chip sits inside the camera, and states: ‘There are potential issues here, as this may cause image quality problems such as distortion and aberration’. Well, that’s just completely untrue and gives readers needless doubts. Some of the lowest distortion wideangles ever made have had very short clearance back focus, like the 21mm Super Angulon for Leica M or the classic 21mms designed for mirror lock-up by Nikon and Minolta – or the 16mm Zeiss Hologon for Contax G.

Some of the world’s best lens designs have used rear elements almost touching the film, including the Ricoh GR (for film), the Minolta TC-1; and the excellent Sony R-1 Carl Zeiss zoom also features a minimal gap between its rear element and the 1.7X sensor of that camera, the absence of a mirror freeing Zeiss to create one of the best 24-120mm equivalent zooms ever designed.

In fact the 18mm mount to sensor distance and the wide mount throat combine to offer the maximum possible scope for the makers to design distortion and aberration free lenses of a quality hard to achieve without high costs and large size, heavy weight even for APS-C DSLRs. PP has got it exactly the wrong way round. They have turned a huge positive aspect of the camera into a negative niggle.

Sweep Panorama is described as a function which is ‘not new on a Sony camera’. Actually, this type of Sweep Panorama is entirely new on a Sony, or any camera. This is not a video-composed Sweep Pan, as found on all previous Sony and other compacts. It is a high resolution, auto-stitched, multi-shot panorama of unprecedented size (up to 23 megapixels).

Confusing the issue, PP states that the panorama files are playable on a Sony Bravia 3D TV. This is incorrect. Normal sweep pan (.JPG) files are playable on any HD TV, and are not 3D. The camera(s) have a second entirely separate Sweep Pan 3D mode, which is not a sequence of shots, but a video pan like compacts. The file (.MOT) created is 1080p HD in height, and in a 3D format; and it can be played back on most 3D TVs using the same system as Sony Bravia.

Most of PP’s comments on using the camera are fair and balanced descriptions of its strengths and weaknesses, but once again, language gets in the way of accuracy. The ‘large optics help deliver… detail to the sensor’. What does that mean? Which large optics? The lenses are fairly small. Their size has no bearing on how much detail they ‘deliver’.

‘This is not the fastest camera out there, but with speed priority engaged it’s impressive at 7fps’ – well, actually, it IS the fastest CLC/ILC out there, and that 7fps has no competition from Micro 4/3rds, Samsung NX or Ricoh. The 2.3fps standard capture rate includes reliable AF tracking (certainly not guaranteed when shooting continuous action with the competitors), but this is not mentioned. It would be fair to comment on 2.3fps being a modest drive rate, but the continuous AF performance had to be taken into account when doing so.

‘The general consensus of opinion is that CSC cameras are effectively high quality compacts that deliver DSLR quality. Yet the NEX-5 is still rather bulky and certainly not pocket material’ - conclusion.

‘The NEX-5 takes the compact size of these CSC models down to a new level, as it’s the smallest and lightest of these removable lens models to date’ - second paragraph of the main report, and highlighted pullquote.

I don’t think I need to point out the conflict in these statements. And the day before writing this, I had the NEX-3 with 16mm lens in my shirt pocket.

‘The HDR mode is okay, but it’s not as good as true HDR creation using post-production software’ – not the best comment to make on the most advanced, 6EV range, in-camera HDR system yet seen and one which also saves a non-HDR JPEG of the normal exposure (not mentioned). None of the other multi-shot modes gets mentioned at all; no reference to the Anti Motion Blur or Twilight modes which blend several exposures to create one low-noise, sharp result.

Finally – ‘Most of the CSC products are quite similar in price, especially with lenses that cover the same focal lengths’. Actually, they are not quite similar in price. To get HD 1080/50i you have to spend almost twice as much. To get their equivalent of the 16mm lens… sorry, you can’t.

There is no 12mm f/2.8 pancake lens made for Micro 4/3rds, or any 16mm prime for APS-C. The 17mm offered by Olympus is a 34mm lens equivalent, not a 24mm equivalent. The 20mm offered by Panasonic is a 40mm equivalent. The 30mm from Samsung is a 45mm equivalent.

By glossing over such issues or ignoring them entirely, the PP report omits most of the unique selling (and using) points of the NEX, and the reader is left to assume that it’s pretty much the same as the competition.

I believe the job of a review is to highlight all the aspects of a product which may not be understood fully by the reader, because they are new or unfamiliar; to point out the differences between products, because these differences drive buying decisions. A single feature on a new camera may be the one feature which attracts many buyers. Sometimes, this matters more to the buyer than all other aspects of handling and design. Single features can persuade photographers to change their entire camera system. Just look at Nikon with ultra-high ISO in the D3/3S – or Canon with true 1080p in the 5D MkII, 7D and 550D.

For me, 1080/50i video with stereo sound is important as the only other way to get that in an affordable package is the Canon 550D with external microphone, or the Panasonic Lumix GH1 at around 60% higher cost. The 16mm lens is important – there has never been a 5-element f/2.8 design covering this angle before. The E-mount is important, it allows more potential choice of adaptation to other optical systems (lenses, scientific, astro, micro, you name it) than any other mount. I’ve already ordered my Sony Alpha adaptor (mentioned briefly by PP without further details or comment), plus independent versions for Minolta SR/MD, Leica M39 and C-mount.

APS-C is important too, as this 14.2 megapixel sensor offers the best quality and largest image size in its class.

The PP Overall Conclusion

Ultimately, PP’s Overall Conclusion certainly fits the report, because so much is omitted which would engage and interest their readership, and so much is dwelled on with makes the NEX seem nothing all that different:

‘I wouldn’t recommend the NEX-5 to the more discerning user’, says Darren Harbar while giving the camera 8/10, ‘but for someone who wants a creative point-and-shoot that will give some control without added complication, the NEX-5 is perfect’.

The build quality, design of the lenses, availability of fisheye and ultrawide converters, battery life (or otherwise!), JPEG quality, and many other aspects are not touched on at all in the PP report. Some of these might be negative – battery life can be short, batteries are expensive. Others might be positive – no other system made offers the option of a 12mm (18mm equivalent) wide angle or 10.2mm (15mm equivalent) fisheye at such low cost.

Is ‘I wouldn’t recommend the NEX-5 to the more discerning user’ a damaging conclusion?

PP is certainly not alone in thinking this, but it’s something which should not be said unless you can qualify it by revealing what you would recommend to the ‘more discerning’ user. Think about the language again; above all, it’s the language of the PP report which will colour the readers’ opinions. What does ‘more discerning user’ actually mean?

As it happens, I’m a fairly discerning user; I can tell the difference between the qualities and capabilities of the many cameras I use, I am capable of making judgments, I have the ability to compare and make choices. I can pick the right tool from the rack. Sometimes, I do want a point-and-shoot that will give some control with added complication, just like PP says.

As it also happens, I want a point-and-shoot which can capture high quality 1080 Full HD video  (preferably 24-25-30p, but 50i will do) with excellent quality sound; I want more than 12 megapixels for stills, 14 is fine, 18 would be even better; and if anyone had put a list of possible lenses in front of me, a 24mm f/2.8 equivalent would have been ticked without hesitation.

It was the lens I could never get, or afford, for Leica; it was my favourite fixed focal length in manual focus SLR from the moment such lenses became available around 1974. 24mm f/2.8 was one reason I dumped the Pentax system and bought into Minolta back then; it was the first lens after the 35-70mm f/4 ‘kit’ and the 50mm f/1.7 that I bought for the Minolta AF system in 1985. 24mm wide reach was the reason I pre-ordered the Carl Zeiss 16-80mm for my Alpha 100 in 2006, and it’s the reason I like the Nikon 16-85mm and the Canon 15-85mm best of all the kit zooms for those systems. It’s even the reason I use a vintage 1999 24-85mm Minolta lens on my Alpha 900.

My conclusion

My NEX-5 with 16mm and 18-55mm OSS lenses cost me £679, but that price included a free stereo microphone which sells everywhere for £99. The built-in mics are so good I might not need it (the camera can record clean sound even if placed just a metre away from a PA speaker blasting out live music – try it with a Nikon D5000 or a Canon 550D). But it makes the two-lens kit cost a ‘real’ £580.

‘Worth the asking price’ is PP’s comment. Worth? It’s the bargain of the year, and that is at launch prices which inevitably fall later on. If you want the wide-angle capability, it’s on its own, and if you prefer the angle of a 28mm-equivalent view, you have 14 megapixels to be cropped down and still match the pixel count of Micro 4/3rds.

NEX has real weakness if you are looking for telephoto reach, and many point-and-shoot upgraders will have been used to surprising long lens equivalents; 300mm is nothing. Micro 4/3rds can get you to to that 300mm equivalent in a similarly priced kit, though without the same wide-angle end. This would have been a useful and valid point for the PP review to raise, of value to readers; don’t buy NEX if you are into safari parks, garden birds, or next door’s bedroom windows. When the 18-200mm OSS does arrive it will cost more than a complete Olympus kit with E-PL1, 14-42mm and 40-150mm – it is also a VERY large lens. There is no neat little 55-200mm OSS for NEX, as there is for Alpha, Nikon and pretty much every interchangeable lens system made whether CLC or DSLR.

Every time I use the NEX-5 I find points to criticise. That rear jog wheel has a tendency to change my selected A mode aperture setting when I pop the camera into the small bag I’m using, forgetting to turn it off first. There I am shooting at f/6.3 and the next time I use the camera it’s at f/22. I wish I could tilt the screen vertically, not just horizontally; I love the screen on my Nikon D5000, and the NEX would have been so much better with the D5000′s design. You could even have turned it to face the camera, protecting the screen and removing distracting displays when using the 16mm optical viewfinder. But no, it’s like the A350-550 series, and fairly limited by its hinged articulation.

When reviewers pick up on points like this, it helps the camera makers. In a magazine like PP, hugely influential, such observations can change the course of future camera design for the better. I don’t find a single observation in the Practical Photography August 2010 issue review of the NEX-5 which stems from the critically aware experience of using the camera or treads the risky ground of daring to compare it directly with competitors.

The European press launch

David Kilpatrick recorded the proceedings at Le Meridien Lav Hotel, Split, Croatia on March 11th 2010 using a Zoom H2 portable digital recorder. Shirley Kilpatrick transcribed the audio, with subsequent editing to translate verbal output to read well as text. This is a multi-page document please use the PAGE navigation at the foot of each page to continue reading. It is a very long document.

Nick Sharples, director of corporate communications for Sony, Europe, welcomed the press to Split in Croatia, and thanked everyone for getting up before breakfast – especially those from Portugal who arrived at midnight (volcanic ash delayed their flights). The launch was synchronised round the world, hence the 8.00am timing for the European meeting.

Yoshiyuki Mogami (Vice President of Digital Imaging, Europe) was introduced to explain a little bit more about the business strategy for Digital Imaging in Europe. Yoshiyuki thanked everyone for coming over to Split; the team from Munich had arrived by driving ten hours.

Sony started Alpha business in 2006, he said, introducing the Alpha 100 in Morocco. The Alpha 700 was launched in Italy in 2007, the Alpha 900 flagship model was introduced in Scotland in 2008. “We have carried out surveys asking people in Europe which brands they would think of when buying a digital camera; the figure has risen from 50%, to close to 70%. Now we are enjoying a 15% market share in Europe. This figure is OK, but Sony now really has to go to our next step.

“But looking at the DSLR as an industry it’s not like two years ago or three years ago. DSLRs were pretty much a booming industry, and that’s why everybody came into his segment. These days the growth of this segment has very much flattened, and of course you could say this is due to economic slow down or recession, but we suspect that the traditional DSLR has a limit in mass appeal to consumers.

“So that’s why Sony can try to break this type of barrier. We put together all kinds of voices and views on this technology to see what we can do – we think we have heard the customers’ voice, and really put it into this project.”

Mogami-san introduced Toru Katsumoto, senior general manager of Alpha:

“Today I would like to officially announce our new ultracompact interchangeable lens camera we have already shown at PMA in February and in Japan. In the current market the boundaries between the three categories – DSLR, compact still camera and camcorder – are already starting to merge.

“In the area when DSLR and Digital Still Compact merge, we see great possibilities. Let me introduce to you NEX-5 (he holds up the camera, in front of large projected images of the cameras). This beautifully crafted body is designed to bring out the presence of the lens. The body is so slim and compact but without sacrificing any size or balance. The grip on this camera ensures a firm and comfortable hold despite such a slim and compact body. The rigidity and texture of magnesium alloy gives a high grade appearance and solid feel to the camera.

“NEX-3 is designed for a more casual approach, and can be very attractive especially for those who have yet to explore the world of the DSLR. The slim design comes in three different colour variations, with a unique texture on the grip. It simply feels great in one’s hand in addition to being a stylish camera.

“The key concept of NEX-5 and NEX-3 is to combine the best of both worlds – the image quality and power of expression of the DSLR, with the portability and ultra-compact design of a digital compact camera. We strongly believe that NEX-5 and NEX-3 are cameras that are capable of satisfying customers’ needs from both DSC and DSLR segments. Namely, compact digital still camera users who are motivated to step up from DSC, and DSLR users who are demanding a more compact camera without compromising DSLR power.

“Professional quality in your pocket is the buzzword for this camera. There are six elements:

• DSLR quality in still and moving images
• Compact and stylish
• Power of expression derived from interchangeable lenses
• Making creative work easier
• Beautiful high definition movies easily filmed
• High speed continuous shooting, 7fps

“The APS-C sensor successfully packs DSLR quality in a small body (he removes the lens and shows the sensor). The new sensor is significantly larger than the FourThirds sensor, resulting in a higher pixel count and superior picture quality.

“Our designers have done a great job; the philosophy is a minimalist design. The lens itself is small, but the body size is so small that the lens looks dominant overall. With the pancake lens, it comes close to the size of a point and shoot camera. It is the world’s smallest, and is lighter than either of the rival brands (Olympus and Panasonic profiles shown on screen but not named).

“The depth of the flange back on the camera is 18mm, the world’s thinnest. This is why we can make it so slim. There are three new lenses. Also conventional Alpha A-mount lenses, currently in customers’ hands, can be used via our mount adaptor.”

Katsumoto-san described the user interface with its virtual scroll wheel, adjusting depth of field; and the sweep panorama including the 3D function. “During the sweep motion, the camera generates two pictures, one for the right eye and the other for the left. You do not need two lenses for 3D.”

He said that Handycam experience had been used to set up high definition recording. Toru emphasised the value of Alpha NEX division working together with other Sony technologists.

“NEX-5 and NEX-3 are only the first two products to be offered by Sony in this emerging area. We believe that products based on the combination of a large imaging sensor and interchangeable lenses are not limited to NEX-5 and NEX-3; today, let me take the opportunity to reveal our second proposal to you briefly. As I am speaking now, a dedicated group of engineers is in the process of developing a new camcorder with the interchangeable lens system (he shows a mockup image).

“This camcorder will come with an EXMOR HD APS-C sensor for DSLR quality video in AVCHD form. Like the NEX-5 and NEX-3, with an adaptor, this new camcorder is also compatible with current Alpha lenses allowing videographers to access a wide range of high performance lenses to be used to express one’s creativity like never before.

“Needless to say, its body design is specially optimised for video shooting. Details of this product will be communicated soon, I’d say around the Autumn area, so please stay tuned. The combination of a large image sensor and interchangeable lenses can create whole new dimensions and expression and possibilities.

“To express our strength in such products, we would like to introduce the phrase “Beyond Our Eyes” which contains the following meanings – bringing new experiences, and style of unforeseen dimensions, that evoke deep emotions, and creating a visual world beyond how our eyes can see in both still photography and video.”

After this, the conference was officially over, and journalists were asked to re-convene for region specific in depth meetings. The meeting for the UK and Scandinavia was headed by Paul Genge of Sony UK. See next page.

The Leica M and screw mounts, with under 1mm difference between them, are 10mm greater than this at around 28mm. Screw mount Leica lenses can be adapted to M even though there is only 1mm difference. With 10mm difference, almost any lens ever made for any camera – even the Robot system, original Contax, maybe even the Pentax 110 SLR – can probably be adapted to fit the E-mount. In fact it will accept 16mm and 35mm (half-frame) ciné, C-mount CCTV lenses, and subminiature camera lenses.

You name it, the NEX will be able to do it. Telescopes, microscopes, endoscopes, whatever. And Alpha lenses, and MD lenses. There is even enough ROOM with over 25mm the spare to fit a true retrofocus format reduction converter – that is, a 0.66X optical unit which condenses the image from a full frame lens to fit the APS-C sensor. It is already done in the video and ciné world, and these converters have a wonderful bonus. Your 24-70mm f/2.8 SSM lens becomes, with a 0.66X reducing converter behind it, a 16-46mm f/2. That’s right – the same way a teleconverter loses you a stop or two, a format reduction converter gains you a stop.

The same converters also increase resolution, much as teleconverters reduce it. Zeiss can achieve 400 line pairs per millimetre from high grade 35mm format movie lenses when rear-converted to reduce on to 16mm or video.

Will Sony ever make such a converter? Do they even know that Zeiss have designs, and make exactly this type of converter for Arriflex and other systems via Angenieux? Do they realise that rear fitting format-reduction converters can also perform an AF function, allowing a manual focus lens from Nikon, Canon, Contax, Minolta or whoever to be mounted on a converter which has an ultrasonic AF mechanism of its own?

Imagine that – your 50mm f/1.2 Rokkor becomes an autofocus 33mm f/1.0 on the NEX. This is not blue sky thinking, it’s an optical practicality not a mere possibility. However, you don’t want to know the price of Zeiss converters, and for a system like NEX a universal converter might never be possible; it might have to be matched to the prime lens.

The NEX mount is almost as wide in the throat as an SLR mount; for some obscure reason, Sony chose to measure the outer diameter of the flange, which is not what matters, and came up with 62.6mm for the Alpha and 58.9mm for the NEX. Inner diameter of the bayonet, the bit which counts, was not stated. But it’s a wide throat and can cope with a huge potential range of adapted lenses.

Less of this ramble, and on to the plain vanilla – the camera.

Inside the camera there is a 14.2 megapixel CMOS sensor, capable of HD video and of course the vital live view and contrast-detection focusing on which the entire camera is based. This is fed to a 3 inch, 920,000 pixel TruBlack articulated rear screen and the user must compose, control and review everything on this screen. There are few buttons, no dials except a single control wheel, and everything is converted to a virtual control or a menu choice using a Sony-Ericsson developed graphical user interface.

The NEX5 camera, by some way the preferable model of the two, has a magnesium alloy body which matches the machined and brushed aluminium barrels of the lenses. It comes complete with a tiny camera-powered flashgun, screwed into an accessory slot on the camera top which has more contacts than a mere flash should need. Three, at least, must be for the stereo microphone audio interface which also draws Electret Condensor Microphone phantom power from the body’s battery.

At the end of less than 24 hours with the camera, I cleaned the white table on the hotel balcony and took a few pictures which will show you the camera in detail.

Here, you can see the 18-55mm f/3.5-5.6 OSS (stabilised) kit lens to the left; the camera body is fitted with the (raised) flash and the 16mm f/2.8 E-mount non stabilised wide angle pancake lens. In front is a 49mm fit lens cap (for either), InfoLithium battery good for around 350 shots, a 4GB MemoryStick Pro Duo MkII, and the lens hood for the 18-55mm.

The NEX baseplate view reveals the steel tripod bush set into the mag alloy casing, the lens release in a slightly unfamiliar position, the size of the grip and the location of the new Sony factory making this system – in Thailand. It was rumoured that these lenses would be branded as Zeiss. Having used these two, I can’t say they would ever have deserved that. Both are very sharp centrally but pretty soft at the edges unless well stopped down, and both have fairly strong CA. The central sharpness is excellent, about as good as you could expect, perhaps aided by the Contrast Detect focusing which is entirely free of back or front focus.

Here’s the body, which is 24.2mm thick at its thinnest point, with the lens removed – the sensor is exposed. But that’s how it normally is, whether switched on or off. Turning the camera off does not closed the focal plane shutter (30s to 1/4000th, X at 1/160th, vertical travel). Dust removal is not going to be all that easy with the sensor cover glass sitting so well shielded and recessed behind the shutter gate. When a lens is fitted, the sun can come in and focus itself on the sensor. What issues will that cause for anyone careless enough to leave a NEX with a 16mm f/2.8 lens on its back, with no lenscap, in tropical mid-day sun? As people sometimes do, dining or drinking outdoors?

The lens will afford some protection when fitted. The well-machined metal mount should not admit dust too easily. There are ten contacts on the E-mount lenses (note the legend ‘E-mount’ etched on the flange). They transfer EXIF information about the lens, power for the ultrasonic focusing motor which is a silent ring type, power for the aperture adjustment via a stepper motor, and command and feedback signals to make these adjustments. Enough of the protocol is shared for the E to A mount adaptor LA-EA1 to have been designed to operate SSM and SAM Alpha lenses. At the launch conference, Sony admitted their engineers had failed to get reliable focusing, so AF was disabled in firmware. They hoped that a firmware update would restore the planned AF functionality with in-lens motor Alpha glass.

The ability to change aperture during video shooting is only offered with E-mount lenses, and is disabled when A-mount lenses are fitted via the adaptor. Sony does not make it clear whether different apertures can still be preset, before filming.

This is one of the lenses which might have proved interesting on the NEX – the Sony SAM 30mm f/2.8 1:1 Macro. You can see the difference in scale and engineering approach. Note the AF/MF switch on the SAM lens – it’s the only way to over-ride AF on the Alpha bodies. The E-mount lenses are far superior, they have full time manual focus over-ride which is ultra smooth, just turn the focus ring at any time to shift away from the autofocused point. When you do this, the rear screen instantly and automatically switches to an enlarged view to aid manual fine focusing.

Here’s a close-up of the 16mm lens iris. Whatever shape of aperture is claimed, there are only seven blades (probably to keep the action very light) and that minimum f/22 does not look especially circular to me – much like any other lens with a very small iris diaphragm. The blades are oddly asymmetrical too.

Here you have the 18-55mm naked on the body. It’s a really good cosmetic match but you can see how large even this lens is compared to the camera. The 18-200mm f/3.5-6.3 which was not ready to be tried out is even larger. Note the position of the strap lug(s). They are placed down the body and angled so that when neckdangled or shoulderslung, the camera tends to hang with the lens aiming down and the screen facing up. This saves a lot of screen scuffing, gives quick access to the info there presented, and keeps the bigger lenses neatly placed.

Be warned, though, that you can’t expect to grab a shot from hanging position. If the camera is turned off, it takes a short delay to fire up and for the screen to brighten as the gain is adjusted (always from dark). If the camera is sleeping, first touch on the shutter button does the same, with the screen ready for use in a second or so. Then a firmer pressure acquires focus and re-adjusts the screen exposure; AF officially takes 0.3s, but I found you could easily have 2-3 seconds from the moment of raising the camera to being able to fire the shutter in confidence. I actually think my old Konica Minolta Dimage A2 is faster. I missed several candids and moving subjects when testing the NEX5.

This is just a shot with the petal lens hood fitted. You may notice that the 16mm lens, supplied without a hood, does have a bayonet as well as a 49mm filter thread. This is to enable two afocal front lens convertors to be fitted – the VCL-ECU1 is a 0.75X rectilinear converter, turning the 16mm into a 12mm ultrawide, while the VCL-ECF1 is a 0.62X fisheye converter creating a 10mm full frame curved view fisheye. Given that the 16mm is expected to be only around £200 (or much less in effect when bought with a body), and these converters are £100 and £120 respectively, a system will be no great weight on the pocket.

There is also an optical finder for the 16mm, which occupies the flash/mic shoe, and will cost £130. Eh?

Like the flash, shown above, it will use the 12-pin gold plated connector and thumbscrew to attach. But it’s not an electronic finder. No-one would answer whether this contact array will support an EVF attachment.

This is how you secure the flash, which stows by folding down flat. Raising it, as in this shot, turns it on.

This runs off the battery, which lives next to the dual-purpose card slot. Previous models have had twin slots. The NEX range uses a dual MSPro/SD slot which auto senses the type of card being used. An AC mains adaptor is available which uses a dummy battery and a cable emerging through a hinged portal in the battery door (above).

The rear screen is articulated very much like the Alpha 550, and does not turn to face forwards, or orient itself in any way to suit vertical compositions. It is very much geared to the landscape format trend created by video shooting, HD, mobile phones and so on. Though the camera has auto orientation sensing for photos, the display does not change like an Alpha and it’s not really designed well for vertical shots.

The downfacing position is pretty odd. It does not fold out in the usual way. I was able to shoot well enough holding the camera overhead. The screen articulation is, like the 550, a very rugged metal mechanism. It does not feel as vulnerable as many other (more versatile) swivel and tilt rear screens.

The GUI is exactly what GUI means – very much a graphical, not textual, user interface. The six main menu icons resemble mobile phone menus. You get to them by rotating the scroll wheel and pushing its centre button. Shortcuts are marked at the compass points of the wheel for outer rim press-clicks taking you to different options or changing the display mode. The LCD has a glass cover but Sony still offers both hard and adhesive protectors. I took photographs using the ‘Sunny’ brightness setting, not Auto. ‘Sunny’ really boosts the backlight well beyond the auto brightness maximum.

The Brightness/Color Menu includes the options for DRO+ and for HDR shooting. HDR is now three frame bracketing, with manual control up to 6EV span (plus/minus 3). The NEX has a very powerful new BIONZ processor and crunches 3 raw files into an HDR JPEG instantly – while also saving, at the same time, the middle bracketed exposure from your rapidfire 7fps burst as a standard choice. So you get two frames from your triple shutterburst, one normal, one HDR. There are also six-shot Night Scene and Anti Motion Blur modes, which synthesise a final low noise or minimum blur JPEG in-camera; I failed to test these, as the presentations made no real mention of them.

Here you can see the second shutter release, marked MOVIE. Press this and there is no waiting – filming starts immediately, so you either need to be in Continuous AF mode, or have pre-focused using the main shutter release. A second press ends the take. Unlike almost every other HD Video 1080p capable model yet made, the NEX5 will shoot continuously without clip length limits, up to around 29 minutes (filesize limit).

Select Shoot Mode, and an image of a virtual mode dial appears concentric with the control wheel. It turns in perfect sync with the wheel. So, without having a physical dial, Sony has given you one. Text information appears as you perform changes. Some more annoying repetitive cyber-advice can be turned off; other ‘tips’ are not optional. They follow you round for life.

The camera includes many functions aimed at happy young exuberant target-market users. I don’t think it is complete, as the Smile Detection menu has not made adequate allowance for Goths, neo-punks, or grumpy old folk with permanently inverted scowls. A future version for the legacy Alpha-owner generation should include ‘Not Frowning’ as a smile mode!

The Display mode change options include a semi-graphical exposure scale exactly along the lines of current Alpha models.

Alternatively, you can opt for a different set of info more aimed at the advanced user. I found that no matter what display mode I used, the screen became so cluttered I sometimes could not see parts of the subject I was keen to check for alignment, cut off or inclusion in the shot.

This – a very simple display indeed – was what I found most acceptable. It is interesting to note that with the exposure metered live from the CMOS, there was much less need for the plus-minus over-ride function using NEX. I was shooting raw, but even the JPEGs obtained alongside the raw files were pretty much perfectly exposed every time. For difficult subjects the JPEG-only shooter can use a three-shot HDR in-camera process, and this worked very well.

I have a gallery of 48 full size in-camera JPEGs taken during the photo shoot opportunity organised for the press, which involved two hours in sealed dirty-window ferry and bus plus half an hour wasted on a wine tasting (?!) session, for the sake of maybe an hour of pictures. They would have been better just bussing us into Split old city and telling us to meet later. Escorting a gaggle of journos round Hvar town was singularly unproductive!

48 full size in-camera JPEGs with peculiarly deficient EXIF data. Where it says 16mm, the 16mm was used. Everything else is on the 18-55mm. The NEX5 body was used.

The NEX system and the initial 3 and 5 model cameras needs much more writing about it, with many new functions and features. This has just been a small guided tour of the camera for you to see it in detail. We will be posting further reports as time permits, rush-blogging not being something I intend to do when there is so much detailed information to be digested. My quick reports from Croatia and during transit back home have already appeared on the BJP website:

The latest news is that Tokina is to introduce the 11-16mm ƒ2.8 in Sony Alpha mount. Tokina stopped making Minolta mount lenses shortly before their parent company Hoya acquired Pentax. The Tokina factory has been producing Pentax lenses (not all of them) and also the Schneider-Kreuznach branded range for the Samsung GX Pentax clone DSLR system.

Now that Samsung has gone its own way with the N-system, abandoning Sony sensors and Pentax lenses, some of the conflicts which possibly inhibited Tokina from returning to the Alpha mount have disappeared – and some of the capacity and market share taken up by their Samsung contract likewise. Alpha lenses will fill the gap nicely.

Sony must, surely, have observed that the Tokina 11-16mm ƒ2.8 is not just the best such wide-angle currently made. It’s also the only one which activates the ƒ2.8 central double cross sensor of the Alpha 700 properly, doubling the focus accuracy which is critical with such short lenses. Depth of field may be huge, but depth of focus (the tolerance at the sensor plane) is not. Calibration needs to be perfect with lenses like this. The 11-16mm could be a perfect match for the next generation of Sony 700-level camera with one or more ƒ2.8-capable AF focus points.

Tokina has made lenses for the Alpha system in the past. They designed, and produced exclusively for Minolta, the 100-400mm ƒ4.5-6.3 APO AF lens. They made one variant of the 28-80mm ƒ3.5-5.6 kit lens, regarded as the best optically. It is possible that Tokina also designed the 100-300mm ƒ4.5-5.6 APO (D) and one or more of its predecessors, whether delivered to Minolta in element form for assembly or not. I would also suspect that odd and much acclaimed one-off, the 35-200mm ƒ4.5-5.6 Xi Power Zoom, of origins outside Minolta. Tokina would be the most likely source.

So it is not out of the question that Hoya/Tokina is once again involved in working with the Alpha system, this time with new owners Sony. The 11-16mm might perhaps even appear in a Sony guise. After all, Tamron has been allowed to continue selling Alpha mount 11-18mms despite making a Sony branded version. Why should Tokina not be able to market their own, while also creating a Sony SSM or SAM version?

I was able to test the Tokina 11-16mm on a Nikon D90 (same basic sensor as the A700, A500 in terms of resolution and physical size) thanks to professional photographer David Bryce, during a seminar held in Scotland in Autumn 2008.

The brief test

David Bryce was one of the first to obtain a Tokina 11-16mm ƒ2.8 zoom, and I had a chance to take a good look at it during a Master Photographers Association Scottish Region seminar in 2008. In addition to trying it out on the Nikon D90 with architectural subjects (the venue, Solsgirth House) I was able to make some full aperture and ƒ4 tests of no pictorial merit, positioning details in the corners to check out how well it performs. If you click on most of the images, you will be able to access full size 12 megapixel files.

Here’s the subject – using converging verticals and a very close viewpoint, at f/9 and 11mm, in nice sunny conditions. The sun kindly disappeared for the straight-on tests of wide open and f/4 performance.

11mm at f/2.8

16mm at f/2.8

11mm at f/4

16mm at f/4

There was some sign of softness in the corners which was not fully removed even by ƒ11. What was surprising was the relative lack of vignetting – even at ƒ2.8, the corners were well illuminated. Performance on Canon’s 1.6X sensor (substantially smaller than the Nikon 1.5X sensor) will appear a little better as the extreme corners are not included.

Uncorrected at 11mm (click image for a larger, but not full size, view)

Corrected in Photoshop (Distortion>Lens Correction) with 3% de-barrelling

The lens turns out to have very good flare resistance, and better geometry than might be expected, needing only 3% correction for pure barrel distortion at 11mm. On most distant subjects, or buildings photographed to allow convergence rather than correct the verticals no correction is really needed.

Compared to Nikon’s 18-105mm VR lens, the Tokina had higher contrast and produced a more punchy image. Both lenses at their widest needed a similar CA correction in Adobe Camera Raw of around -30 Red/Cyan defringeing, and the Nikon showed more vignetting. On revisiting the files, I found the Tokina could survive with -20 CA correction and was generally cleaner than the 18-105mm. I’ve since bought an 18-105mm VR Nikkor myself and can confirm it’s a modest performer optically, but cheap.

16mm at minimum focus, f/8, into the light with a very bright sky

Close focus was impressive, more useful at 16mm than 11mm, with not too much field curvature or corner sharpness loss. The close-focus shot also shows pretty good bokeh, and being taken directly into the light, well controlled internal reflections with no veiling glare over the shadows.

For most medium and long distance subjects, full aperture would not produce an acceptable print. The 35mm shaped frame would need to be cropped to 10 x 8 shape to lose unsharp zones at the ends of the shot. The centre, even wide open, is exceptionally sharp. At ƒ4 there is a small improvement but not enough to make the full frame useful.

Interior at f/8, 1/30th. The Nikon D90 has no sensor stabilisation and the Tokina also has no IS/VR. You can see the degree of barrel distortion present at the frame end (the example above shows it on the long side, this displays it on the short side. The good news is that although it is strong barrel, it is simple, not moustache-shaped wave form distortion. This means a simple correction can fix it, no need for a lens geometry map.

By ƒ8 sharpness is good across the frame bar the extreme corners; these may demand ƒ11, an aperture which now begins the soften the whole frame as a result of diffraction. Even so, for architectural or industrial shots, ƒ11 would be a suggested setting to get corner to corner sharpness at 11mm. With the right subject and precise focusing, wider apertures may produce perfect results, as the very ordinary shot below shows.

Normally, I either wouldn’t put up an image with a badly angled composition and poor lighting like the one above – at the least it would be cropped and straightened. However, this particular shot at f/7.1 and 11mm must have been optimally focused (I’d guess, on the gravel not the house) and shows what the Tokina can do when the depth of field is adequate. The grass is sharp pretty much to the extreme corner. Click to view the full size file.

The centre to edge difference at full aperture is emphasised by the unusually high resolution on-axis. The ƒ2.8 aperture enables extra accurate focusing with most DSLRs including the D90, and this really pays off in terms of micro-contrast and detail.

We do not yet know how Sony will tackle the problem of ensuring accurate AF with rising resolution values. It is a more complex subject than I thought possible, with everything from the focal length and aperture to the design parameters of each lens affecting accuracy. AF point (front or back focus) even changes with temperature, more so for outer field sensors than the central point. The Canon 1D MkIV has a temperature sensor in its AF module to apply recalibration on the fly and correct for the differential expansion of silicon and glass components of the AF array within its working temperature range.

There is one surefire way to get perfect wide angle focus – contrast detect focusing from the imaging sensor itself, or for Alpha system owners (so far), Manual Focus Check Live View on the Alpha 550 and 500. The Tokina 11-16mm will be perfect for this method as the wide aperture will show the correct focus point clearly.

The Alpha System celebrates its Silver Jubilee or 25th Anniversary this month – though left uncelebrated by the inheritors of the Minolta AF legacy, Sony. They have no reason to draw fresh attention to the age of the system, as in four years they have taken it the same sort of distance that Minolta took the world’s first AF system in the late 1980s.

It’s not only Alpha’s 25th birthday. This is also the 25th birthday of modern AF SLR systems – all of them!

This is a multi-page article. See the links at the bottom of the page to Continue Reading after each page.

For Photoclubalpha and the historic Minolta Club of Great Britain, the anniversary does matter. A good many of you out there have been members since the launch of the system, often using the earlier SR and X manual focus systems before that. We still have a 1985 Minolta 7000AF and it’s still working just as it did when new.

25 years before the first Minolta SLRs appeared – a folding Minolta Six of 1935

I don’t mind showing my age to make a comparison. I was 11 in 1963 when I took my first pictures with an SLR camera. My father had bought himself a Pentax S3 – and the camera it replaced was 25 years old, a pre-war Zeiss Ikon Kolibri collapsible 16-on-127 model.

When the Kolibri was made, 127 was the ‘vest pocket’ format of choice. 35mm was on the rise, but 35mm SLRs had not yet arrived. They were as much a thing of the future as digital SLRs were when the Minolta 7000AF was launched.

But within that 25 years, there was hardly a single camera system made with interchangeable lenses that did not become obsolete. Only the ‘frozen assets’ of the cold war kept some systems, like the Exakta bayonet and the Praktina, alive. New brands were launched, from the British Wrayflex and Periflex to the Italian Rectaflex and many German oddities. It was not unusual for an entire system to be come and gone within a few years.

Even in the following quarter-century, the high years of the Japanese 35mm SLR, the succession of lens mount changes was bewildering. Independent lens makers like Tamron and Sigma were forced to make systems using interchangeable mounts not just because the public wanted it. A dozen or more mounts were made for every lens and in the 42mm screw thread fit alone there were endless variants – Praktica LLC (Pentacon Electric), Olympus FTL, Pentax ES and more.

It was more or less a 25-year cycle – the SR system was announced in 1958, and really got underway by 1960. It was to be another quarter century before the AF system arrived. We are now a further 25 years on – can we expect a totally new camera system, once again, in 2010?

Minolta’s SR bayonet mount, introduced in 1958/9, actually remained basically unchanged all the way through to 2005 when the last manual focus model, the X-370S, was available. It survives even now as a mount popular in China where the Seagull range from Shanghai Optical includes Minolta fit models. That mount only ever had one major revision, to add a linkage for open aperture TTL metering. The introduction of programmed exposure and shutter priority was cleverly enabled by using the existing design of lens mechanism and improving its accuracy, while adding a simple reference lug to the ƒ-stop setting ring.

Nikon’s 1959 F-mount proved similarly easy to improve without any basic modification. Both these bayonet mounts celebrated half a century of production in 2008/9 – another landmark, which Nikon was able to celebrate but Minolta of course could not.

This review has been updated August 2010 – see the second to last page for new Adobe Camera Raw Process 2010 results, a massive improvement with Alpha 550 files.

The 500 was promised to me a week before writing this, but has not been sent by Sony. The Alpha 550 is mine; they have not been issued for reviews yet, and to get one, I had to buy one.
It’s both one of the best £600 purchases I’ve made and one of the worst. Find out why!

The literature and application CD included with the Alpha 550

The accessories included with the Alpha 550 – the neckstrap is slightly less sharp-edged than the very cheap version provided with the A200 to A380 models.

I have always valued the superb low ISO performance of the Alpha digital cameras – from Konica Minolta Dynax 7D onwards. The Alpha 100 remains unmatched for the crispness of its detail at ISO 100 when processed from raw, if you are lucky enough to get accurate focus.

The Alpha 350 had the same intensive test treatment that was planned for the 550. I left my Alpha 700 behind, and took only the 350 for a week shooting Gran Canaria. It didn’t disappoint; we knew the high ISO performance was a limitation, but shots at 400 and 800 were commercially usable. Those at 100-200 had a great colour quality and smooth, noise-free sky and neutral tones.

The 700 and 900 have both been a mixed experience. The base ISO 100 image in both cases lacks the finesse of either the Alpha 100/200/230 10 megapixel sensor, or the Alpha 350/380 14.2 megapixel CCD. However, both respond well to using settings or 160 or 320 (not 200 or 400) with Adobe Camera Raw/Lightroom processing.

The Alpha 550 has a 14.2 megapixel CMOS sensor so might be expected to behave a little more like the 700 and 900, with strong anti-aliasing and heavy noise reduction applied to the raw file (in effect) by processes built in to the sensor itself, and the BIONZ processor.

The good news is that all Sony Alpha DSLRs from the 100 on are included in a different list of RECOMMENDED cameras – all are confirmed as being capable of providing adequate images.

Here’s the Cyber-shot blacklist:

Please note at present Alamy does not accept any images from the following Sony digital cameras.

Now Samsung got in there by mistake, I think, but it includes some cameras I once thought were adequate such as the Cyber-shot F-828. Not surprisingly, the similarly specified Konica Minolta Dimage cameras are also blacklisted:

It’s sad to see the A2 and A200 – both providing .MRW raw files which can be of exceptional quality at ISO 64 with careful handling – included in such a list. But this is reality. Earlier this year, I included in our own Alamy submissions a great set of 60 images by my friend Peter Fry who had visited the Caribbean and Central America using a Sony F-828. I liked his people pix enough to feature them in Photoworld, and they reproduced excellently. But they resulted in the first ever total rejection of a batch of files I have had from Alamy.

More controversial is the Alamy list for Sigma – even the latest (or almost-latest) SD-14 and the popular pocketable DP-1 are banned:

Well, in fact I have many images taken on the SD-9, SD-10 and SD-14 on Alamy and submitted as complete batches too, not hiding amongst a submission. My entire set from one trip to Turkey was shot on the SD-9, and all the files were duly taken up to 48MB. They have sold, as well, and no complaints or refunds have ever followed the sales. For owners of the DP-1 expecting to use it as a stock-photo notebook camera, this latest list is a knock-back.

And, in the Kodak list, the DCS760 is blackballed. This beautifully made Nikon F5 based DSLR has one of the best 6 megapixel sensors ever designed, within its limited working ISO range. With a 1.3X factor, it has very large pixels and uses very narrow-cut colour filters producing superb colour quality. I have owned one for a few months, and of course, there are a few Alamy pix from it. I would have to rate the quality higher than my Konica Minolta Dynax 7D or 5D six megapixels in some respects.

Also, the excellent Ricoh GR Digital and GR II are both rejected. Again, I have an entire set of images taken using this GR, an optically superb fix focal length wide angle 8 megapixel compact, which went on to Alamy as a set in the past without question. They are still some of the best-looking files for colour and the performance of that 28mm-equvalent lens. Even the pics with the 21mm-equivalent wide angle converter are up to DSLR standard.

What exactly is sharp enough for Alamy?

Here is an example of what is NOT sharp enough:

This is a picture of Stormont, the Belfast Northern Ireland Assembly building, taken by Ailsa Kilpatrick when she visited the Assembly earlier in the year. She used a Sony Alpha A350 with 16-105mm SAL lens. It’s been straightened up a touch and distortion removed (though it was at the long end of the lens, and this was just a minor verticals correction). Contrast has been increased greatly to give it some impact. The point of focus, as you would expect, is on the columns and facade of the building, but this is the result which Alamy QC rejected, when enlarged to 48MB size (5120 pixels high):

Bear in mind that no capture sharpening or unsharp masking can be used when sending files to Alamy, so some natural softness will be present due to AA filter and deBayer operations. I would have said, looking at the detail shown in the upper egg and dart string of the course above the column’s capital, that although the 16-105mm has produced a slightly ‘dirty’ rendering, it’s well up to the sharpness of any of the 6 or 8 megapixel shots I have filed in past years. But when sent the clip (because this was the image they rejected, taking with it several dozen others which are automatically kicked back if you get one in the batch failed) they confirmed that they upheld their QC decision.

This is no great worry, Ailsa took many other pictures some of which are already accepted and on-line, and many are that little bit cleaner and sharper than this. But when asked, Alamy’s staff stated that standards for QC have not changed. What was once accepted (6 megapixels enlarged to 17 megapixels, the 48MB size required) was still accepted. There had been no shift in standards created by the effect on staff of seeing so many 14, 16, 21, and 24 megapixel files arriving today. I found this hard to believe, because my own standards have changed after using the Alpha 900. My earlier work no longer looks sharp enough!

A few days later, the list of unacceptable cameras appeared on Alamy’s blog. They may not have been willing to be drawn into making any comment about improving standards, but their action speaks louder than words. In the list of non-approved cameras are several mainstays of early Alamy shooters – successful ones as well. The Konica Minolta Dimage A2 and A200, the Canon PowerShot S1 Pro, the Ricoh GR Digital… all these were purchased in their dozens (even sought for on the used market) by travelling Alamy contributors wanting raw files from a lightweight versatile camera with 8 megapixels.

Now that era is passed. If you are planning on trying Alamy, study the example above. It was, I am told, a borderline case but nevertheless not good enough. If you can’t get something visibly better than this (and it makes a perfectly sharp looking A2 print!) don’t bank on getting your Sony Alpha, or any other, images past Alamy Quality Control.

Newly Developed Single Lens Optical System
In existing half mirror 3D camera systems with separate lenses for the left and right eyes, the parallax range is adjustable, enabling the depth of the 3D images to be modified .  However, when operating the zoom and focus functions of such systems, the sensitivity of the human eye, in particular to differences in the size and rotational movement of dual images, as well as any vertical misalignment or difference in image quality has meant that complex technology has been required to ensure that each camera lens is closely coordinated, and there are no discrepancies in the optical axis, image size, and focus.  The introduction of a single lens system resolves any issues that may occur as a result of having different optical characteristics for each eye.  Furthermore, by using mirrors in place of shutters, incoming light can now be simultaneously separated into left and right images and recorded as it reaches the parallel light area (the area where diverging light from the point of focus on the subject matter becomes parallel) of the relay lens.  The separated left and right images are then processed and recorded with the respective left and right image sensors.  As there is no difference in time between when the left and right eye images are captured, it is possible for natural and smooth 3D images to be captured, even of scenes involving rapid movement.

240fps 3D Filming
Optical tests have shown that a frame rate 240fps represents the limit of human visual perception, and beyond that it becomes difficult to detect differences in terms of blur and “jerkiness” of moving images (where images that were continuous are now seen as a series of distinct snapshots).  By developing a 240fps frame rate CMOS image sensor with properties close to the human eye, which is capable of capture natural images of even fast moving subject matter, Sony has succeeded in further enhancing the quality of 3D video images.

The combination of Sony’s new single lens 3D system and its 240fps high frame rate technology has realized a single lens 3D camera system, based on universal properties of the human eye, which enables natural and smooth 3D images with no accommodation-vergence*1 conflict to be recorded.

Technological Features
1. New single lens optical system
- Captures left and right images simultaneously to deliver natural and smooth 3D images with no accommodation-vergence conflict.
- Eliminates the need for lens synchronization, ensuring easily accurate control of 3D zoom and focus functions.
- When polarized glasses are not used, viewers with still be able to see natural 2D images, as the disparity of the images for left and right eyes are within the range that human eyes can recognize as a blur.

2. 240fps image capture to realize high quality motion images
- Realizes high quality capture of 3D content including fast-moving subject matter such as sports.
Prototype to be demonstrated at “CEATEC JAPAN 2009”

Within the growing 3D cinema industry, Sony has supported and driven the expansion of 3D by providing a wide variety of professional equipment for the shooting, production and screening of movies in 3D.  The number of digital 3D screens is increasing rapidly, and is expected to reach 7,000 worldwide by the end of 2009*2  In addition to 3D movies, Sony’s range of professional 3D products and technology is also driving the growth of 3D production and distribution across a range of entertainment industries, from theatre and music performances to sport and beyond.  Furthermore, Sony is also aiming to continue to lead the way in delivering new 3D viewing experiences by bringing 3D to the home in 2010.

Two powerful, feature-packed DSLR cameras from Sony make it easier than ever to capture beautiful pictures, carefree family portraits, stunning holiday memories and action-packed scenes.

The DSLR-α500 (12.3 megapixels) and DSLR-α550 (14.2 megapixels) are packed with advanced Sony technology that combines the spontaneity and freedom of Live View shooting with exciting new features that help to realise your creative vision.

At the heart of both cameras is a new, unique to Sony, Exmor™ CMOS sensor that ensures crisp low-noise images, packed with fine detail and vibrant colours.  Sharing powerful on-chip noise reduction techniques with the full-frame DSLR- α900, this advanced sensor works with processing algorithms handled by the newly developed high-speed BIONZ™ engine to deliver premium images plus razor-sharp shooting responses. Dramatically reduced picture noise now allows super-sensitive shooting at up to ISO12800, achieving great results when shooting handheld in challenging situations like candlelit interiors.

Thanks to the powerful BIONZ image processing engine, Quick AF Live View now supports even speedier shooting responses with rapid, precise autofocus. This makes it easier than ever to capture beautifully relaxed portraits, dynamic action shots and more.

Powered by the BIONZ image processing engine, fast-moving action can now be captured effortlessly with faster continuous shooting speeds. Sustained shooting speeds of up to 4 fps can be achieved in Live View Mode, rising to 5 fps with the optical viewfinder. New Speed Priority mode on the DSLR-α550 raises the bar further still, shooting at an incredible 7 fps (with AF and AE setting maintained from the first frame ). It’s a powerful creative tool for capturing the nuances of a portrait subject’s changing expression or dynamic action sequences.

Creative options are broadened by new Auto HDR mode that captures a huge range of shadow and highlight detail in landscapes, interiors and other scenes. Previously accessible only to enthusiasts equipped with a tripod and image processing software, HDR (High Dynamic Range) is a specialist technique that combines two or more frames shot at different exposure settings. The α500 and α550 use powerful algorithms to combine and optimise two successive frames in only 2 seconds, correcting any misalignment between frames when shooting handheld, which is Sony unique technology. The result is a single HDR image emulating the huge natural tonal range of human vision – with no PC or tripod needed.

The D-Range Optimiser featured in previous DSLR models has been enhanced for even better results with backlit portraits and other tricky high-contrast scenes. The powerful BIONZ engine now optimises image data in real time even in continuous shooting mode, processing brightness and contrast in individual areas of each exposure for balanced, natural looking results. Optimisation can also be selected manually from 5 processing levels.

The α500 offers a crisp, high-contrast 3-inch Clear Photo LCD Plus screen with the same tilt range for clear, comfortable composition and reviewing shots.

The α550 features a superb (921k dot) 3-inch Xtra Fine LCD screen for critical focusing and photo-quality viewing with class-leading colour, contrast and detailing. The screen tilts up or down over a full 180 degree range, allowing uncompromised ‘free-angle’ live view shooting in any position. An ambient light sensor automatically boosts LCD brightness for extra screen clarity when surrounding light levels are high while both cameras also feature a clear, bright optical viewfinder with wide 95% field coverage for framing and focusing as an alternative to live view shooting.

In a DSLR debut, Quick AF Live View now features Face Detection, prioritising AF on people’s faces and fine-tuning exposure/white balance settings for crisp, beautiful portraits with natural skin tones. Another DSLR first by Sony is Smile Shutter, already featured on many Cyber-shot™ models, Smile Shutter detects faces in Live View mode, automatically firing the shutter at just the right moment to capture happy, relaxed smiles.

A special new Manual Focus Check Live View mode assists with fine-tuning your composition. Low-noise images can be previewed directly from the CMOS sensor, allowing critical assessment of focus and fine detail, even in low light. The live image offers 100% field coverage, assisted by framing grid lines for precise composition. There’s also a selectable 7x/14x zoom function for a close-up confirmation of focus.

Operation of both cameras is brilliantly simple, thanks to a redesigned on-screen interface that provides easy access to functions and settings during live view operation. A unique Graphic Display gives a clear, intuitive indication of how shutter speed and aperture adjustments will affect the final image.

A Smart Teleconvertor button instantly boosts image size by 1.4x or 2x to extend your camera’s zoom lens range further for frame-filling close-ups.

Like all DSLR cameras by Sony, both new models feature SteadyShot™ INSIDE, the powerful optical image stabiliser that cuts the effects of camera shake by up to 4 EV steps while shooting handheld with any lens.

After shooting, it’s easy to connect both cameras to your BRAVIA™ television via HDMI (requires optional cable) for a stunning big-screen view of your shots. Compatible BRAVIA™ models automatically switch to PhotoTV HD mode for optimised still image playback with incredible detail, colour and clarity. BRAVIA Sync lets you control image slideshows in comfort via your TV’s remote.

Both cameras let you capture even more incredible moments without the worry of running out of power. The InfoLITHIUM™ rechargeable battery pack (NP-FM500H) of the α500 allows up to 1000 shots (CIPA test, approx. figure) – the highest capacity of any α series digital SLR camera battery to date. The battery of the α550 delivers up to 950 shots from a single charge.

If you’re hungry for even more shooting stamina, the new VG-B50AM Vertical Control Grip holds up to two NP-FM500H batteries. This premium grip gives α500 users an incredible 2,000 shot maximum capacity (α550: 1,900 shots), with automatic switchover between batteries and accurate display of power remaining in % increments on the camera’s LCD. An additional shutter release and dual controls support comfortable, accurate shooting in either portrait or landscape positions.

Also, with Memory Stick™ at the heart of the Sony alpha, you have every advantage. The advanced Memory Stick PRO-HG Duo HX (4GB, 8GB, 16GB or 32GB) is the perfect tool for continuous shooting mode, with the ideal combination of massive storage capacity and blisteringly fast operation. Memory Stick PRO-HG Duo HX 32GB will never miss the key shot because the number of pictures taken in 1 min is approx 270* photos (in RAW+JPEG/L (12M). Delivered with USB Adaptor, Memory Stick PRO-HG Duo HX 32GB is ideal for users who want to transfer data in high speed: approx. 1700[1] pictures in L (12M) size at RAW+JPEG mode in 26 minutes.

The DSLR-α550 and DSLR-α500 digital SLR cameras are available from the end of October 2009.
